The present invention is directed to a skin composition booster oil and a cosmetic composition having enhanced efficacy as a result of being boosted with such oil. The booster oil comprises active solubilized therein and may be added to a cosmetic composition via a dosing regimen. The regimen allows for the control of active strength in the composition topically applied to a consumer.
Dry skin, age spots, as well as wrinkles are just a few of the imperfections that impact a consumer's skin. Personal care products, including creams and lotions, are typically formulated with actives to address such imperfections. Traditional products typically display shortcomings since actives formulated in the products tend to be unstable and/or interact with each other to yield by-products with little to no known skin benefits. It is also true that active instability and interaction often results in a cosmetic composition that can be discoloured, have malodour or both wherein such characteristics would invariably cause a consumer not to continue to use the product at issue.
There is increasing interest to develop cosmetic compositions that have stable actives and that are able to provide superior efficacy to consumers when they are topically applied.
This invention, therefore, is directed to a skin composition booster oil. The skin composition booster oil has active solubilized therein and is suitable to be added to a cosmetic composition via a dosing regimen to unexpectedly result in cosmetic composition with superior active efficacy when topically applied.
Additional Information
Efforts have been made for developing topical compositions. In U.S. Pat. No. 8,124,063, a composition for moisturizing human skin is described.
Other efforts have been disclosed for making topical compositions that benefit skin. In U.S. Pat. Nos. 8,409,550; 8,226,933 and 7,959,913, compositions containing boosters are described.
Still other efforts have been disclosed for preparing skin benefit compositions. In U.S. Pat. No. 8,642,665, environmentally friendly and low whitening topical compositions are described.
None of the additional information describes a composition as set forth in the present invention as claimed.
In a first aspect, the present invention is directed to a booster oil comprising:
wherein oil makes up from 88 to 99.5% by weight of the booster oil, the booster oil optionally comprising structurant.
In a second aspect, the invention is directed to a cosmetic composition having added thereto the booster oil of the first aspect of the invention.
In a third aspect, the invention is directed to a regimen or method for adding the booster oil of the first aspect of the invention to a cosmetic composition.
All other aspects of the invention will more readily become apparent from the description and examples which follow.
Skin, as used herein, is meant to include skin on the arms, face, feet, neck, chest, hands, legs, buttocks and scalp (including hair). End use composition (water or oil continuous but preferably oil continuous) is a composition for topical application and includes a cream, lotion, balm, serum, gel, mousse, deodorant, antiperspirant, shampoo, conditioner, and liquid personal wash. Active means an ingredient that improves a skin characteristic. The booster oil of the present invention is a composition with oil comprising stable and soluble active that may be combined with the end use composition. Polarity index means the value measured of the interfacial tension of an oil taken against water and measured via the drop weight method (M. Alpbaz et al,: The Measurement of Interfacial Tension by Drop Weight Method, Commun. Fac. Sci. Univ. Ank. Serie B, V 34, p 103, 1988). Peroxide value is a normal oxidation index of an oil as measured by standard iodometric titration. Actives not compatible means when present, their combined benefit can be inferior to the benefit each provides alone. Retinoic acid precursor is defined to mean a component that, when oxidized, can convert to retinoic acid.
Unless explicitly stated otherwise, all ranges described herein are meant to include all ranges subsumed therein. The term comprising is meant to encompass the terms consisting essentially of and consisting of. For the avoidance of doubt, a composition comprising the oil, structurant and active of this invention is meant to include a composition consisting essentially of the same and a composition consisting of the same. Stable, as used to characterize active in the booster oil, means active that remains intact prior to being combined with end use composition. All percentages used herein are meant to be by weight unless stated otherwise. Except in the operating comparative examples, or where otherwise explicitly indicated, all numbers in this description indicating amounts or ratios of materials or conditions and/or physical properties of materials and/or use are to be understood as modified by the word “about”.
The only limitation with respect to the active that may be used in the booster oil of this invention is that the same is soluble therein and provides a benefit to skin when topically applied.

When making the booster oil of the present invention, the desired ingredients may be mixed to produce the oil continuous composition having soluble active therein. Typically moderate shear is used under atmospheric conditions with temperature being from ambient to 85° C. The end use compositions suitable for use in this invention may be mixed via conventional methods including those which use standard homogenization techniques. The end use compositions suitable for use can also be those which are commercially available.
In a preferred embodiment, the booster oil of the invention has a viscosity from 750 to 15,000 cps, and preferably, from 2,000 to 10,000 cps, and most preferably, from 4,000 to 7,000 cps, including all ranges subsumed therein, where the viscosity of the booster oil may be measured with a Brookfield (DV-1+) Viscometer, temperature 25° C. and set at 20 RPM, RV6 for 30 seconds.
The booster oil of the present invention typically should have less than 5% by weight water, and preferably, 0.0 to 2.5% by weight water based on total weight of the booster oil and including all ranges subsumed therein. In a most preferred embodiment, the booster oil is anhydrous, and therefore, free of water.
The oil soluble actives described for use in the booster oil of this invention may also be present within the oil phase of the end use composition. Typically, such oil soluble actives make up from 0.0 to 20%, and preferably, from 0.01 to 16%, and most preferably, from 1.0 to 12% by weight of the end use composition, including all ranges subsumed therein. In an especially preferred embodiment, from 0.001 to 6%, and most preferably, from 0.03 to 3.5% by weight of a resorcinol derivative is present in the oil phase of the end use composition with no retinoic acid precursor present therein.
If gels are desired, to the booster oil may be added oil based gelling agents like those comprising lecithin, phospholipids, phytostearol or mixtures thereof. Such agents typically make up from 0.1 to 2%, and preferably, from 0.5 to 1.5% by weight of the booster oil, including all ranges subsumed therein.
The booster oil of the present invention is dosed into the end use composition and typically a consumer is instructed to combine booster oil with end use composition already in the consumer's hand. The same may first be mixed in a small vessel like a reusable plastic cup. Instructions on how much booster to combine with end use composition will be provided so that the consumer, by mixing in his or her hands (stirring or collectively on his or her body), will produce a well-mixed and enhanced end use composition that has intact active ready to apply to skin in need of an improvement. Typically, instructions will be provided to not use the booster oil alone and only in combination with end use composition. Booster dosing may be achieved with a package suitable to release drops or with a package having an eye dropper, preferably with volume marked. Typically, the consumer will be instructed to use from 2 to 8 and preferably, from 4 to 6 times by weight more end use composition than booster oil, including all ranges subsumed therein.
The end use compositions suitable for boosting with booster oil of this invention are limited only to the extent that they may be topically applied to provide a consumer benefit. Superior products made commercially available by Unilever® under the brand names Dove®, Ponds®, Simple®, Vaseline®, Fair and Lovely®, St Ives®, Noxema®, Suave®, Kate Somerville® and the like are especially preferred for use with the booster oil of this invention.
The Examples provided are to facilitate an understanding of the invention. They are not intended to limit the scope of the claims.

The results indicate that when oil and/or active amount is/are used in a manner that does not meet the criteria of the present invention, stability of the actives present decreases.
Booster oil similar to the one made in Example 1 was combined with a commercially available lotion (Pond's age miracle™) to further enhance the performance of the latter. The panelists were instructed to utilize 5 parts of end use composition for every part of booster oil and to combine the components with shear in a reusable cosmetic cup. The resulting end use product was then applied to the panelist's hands to deliver excellent topical benefits. Surprisingly, the composition was easy to mix and apply. The composition did not result in unpleasant sensory characteristic upon application.
